Hello boss.
i was trying getting cocoapods step by step fellowing your tutorial youtube video and it keeps showing errors which are
ERROR: Could not find a valid gem ‘cocoapds’ (>= 0) in any repository
ERROR: Possible alternatives: cocoapods, xcocoapods, cocoa, cocoa-xml, cocoadex
I don’t really know how to soluve that
thx
You already typed in wrong, as you typed in cocoapds according to your error, try doing it again ang make sure everything is typed and spelled correctly
hey but when I typed the code “sudo gem install cocoapods” it is showing the error
ERROR: Error installing cocoapods:
ERROR: Failed to build gem native extension.
so plz tell me if I am wronger problem in my Mac
check the terminal if you are using bash or zhs, you should be using bash for this
also make sure you have and are running as administrator
thanks very much my freind
my terminal is running in zsh so can you tell me please what I have to do if I want to run it on bash and become administrator ?
when I am trying to install the cocoapods I am typing sudo gem install cocoapods in bash in terminal it is showing the error
ERROR: Error installing cocoapods:
ERROR: Failed to build gem native extension.
please help me to how to solve this issue
When the installation fails can you copy and paste all of the diagnostics from the terminal in a reply. There may be other details listed that may be the key to identifying what the cause is.
is it really running zhs? , can you post a screenshot of your terminal as you open it?
when I firstly open the terminal it was running on zsh but now I have set it to bash
when I am typing sudo gem install cocoapods it is showing (the screenshot attached to this reply)Screenshot 2020-12-18 at 11.10.14 AM|690x431 )
There is a stackoverflow thread that deals with an error related to ffi.
The thread suggests that you should perform the following installation in terminal:
sudo gem install ffi
this page doesnot exists… can you please check and let me know the right guidance
The page does exist but obviously you can’t see it which means that you are not a CWC+ member given that the thread is within the CWC+ Students area.
This is the content of the thread:
You are not the first to have issues with cocoapods on an M1 chipped Mac with Big Sur. You and others are getting an error that points towards a missing ffi.c bundle as indicated by the first line in the error messages you posted above that says:
LoadError - dlopen(/Library/Ruby/Gems/2.6.0/gems/ffi-1.14.2/lib/ffi_c.bundle, 0x0009): missing compatible arch in /Library/Ruby/Gems/2.6.0/gems/ffi-1.14.2/lib/ffi_c.bundle - /Library/Ruby/Gems/2.6.0/gems/ffi-1.14.2/lib/ffi_c.bundle
From what I have read the solution seems to be by firstly opening Terminal with Rosetta 2.
Here’s the workaround:
